Scoped rifle
To get a scoped rifle on the first mission, go to the barn where you will see a lot of ammunition. Walk around and you will be asked if you want to swap for the scoped rifle. Take the scoped rifle and get all the ammunition desired. If you run out of ammunition, go back to the barn and get more. The ammunition is unlimited at the barn.
